To all posters who have lost from today:

Firstly, as Mike suggests, check for any loose or damaged cables or connections as any faults in your system could be preventing the channels which have moved being found on their new frequencies. If you are still missing channels such as Pick, Dave or Sky News you should contact the advice line for assistance (some viewers may need a new aerial which will be arranged free of charge if you don't have or ), details can be found at the link below:

The schedule of the 700 MHz clearance changes on the shown on this web site is incorrect.

The correct information is published by digitaluk.

The 56 to 36 move was as listed by digitaluk and no further work takes place this year!

To those having oproblems with receiving certain programmes from , I can assure you that it is not a fault at the as I have all the usual still. As I'm in Trowbridge, I have a Log36 with a powered adjacent to it. I did the retune yesterday after the overnoght work and all is as expected. No channe;s are missing.

So some may have the wrong aerial to cover all the channels, which is why we recommend a log-periodic aerial as that covers all the frequencies used for TV and hence will not need replacing if/when there are further changes in the future.

Bruce: It is a well known that a poor connection in an aerial feed can cause loss of just one group of channels in a . So please do as suggested and check all the leads and connections (by unplugging and then refitting) behind the TV and as far as you can safely reach to the aerial.

BrizzlweRocker:

It is always good advice to check all the connections BEFORE attempting a retune. All a retune will do is wipe all the current tuning stettings and that is not something you want to do if the problem is with one .

Checking aerial connections is something that we television service engineers have been doing for more than 70 years, as even in the days of VHF TV there were problems of corrosion affecting coaxial plugs/sockets causing loss, or poor , of some signals whilst others were perfect.

I did not suggest any work on the aerial other than recommending use of a log-periodic aerial for all reception of all now and in the future.

This info is unhelpfully out of date. Ch56 is now defunct and Dave can now be found on Ch33.

SimonP: The change only took place a few days ago. Have some patience, it takes time for websites to be updated by their owners.
